TIRE.

Application led January 2, 1220. Serial No. 348,797f

To all whom t 'may concern.: l t

Be it known that I, OSCAR Buena citizen of Peru, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Tire, of which the following is a full, clear, and exact description. A

This invention relates to improvements 1n tires, an object of the invention being to provide a tire with an improved tread. or wearing surface' which is made with cementitious inserts which increase the wearing qualities of the tire, prevent slddding and-.prevent punctures and blow-outs.

A further lobject is to provide a tire having projections or protuberances which are made hollow and in which cementitious 1nserts are embedded securely anchored in the tire and located iush with the outer face of the tire so that this material, when hardened, forms an artificial stone insert which constitutes a permanent fixed part of the tire.

With these and other objects in view the invention consists in certain novel -features of construction, and combinations and 'arrangements o'f parts as willv be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure l is a fragmentary edge view illustrating one formof my invention;

Fig. 2 is a view in longitudinal sectionA on the line 2 2 of Fig. l;

Fig. 3 is a view in transverse section on an enlarged scale on the line 3 3 of Fig. 1.

1 represents a shoe ortire having projections or protuberances on its tread or wearing surface. The tiremay be manufactured in any way desired, but is preferably formed as is customary in the art and may be made of laminated fabric with rubber and vulcanized to give the necessary structural strength and stability. My invention is applicable to any ordinary form of tire construction and is not limited to the particular manner of making the tire.

The projections 2 illustrated in Figs. 1, 2 and '3, are of circular form and are made hollow vso as to form pockets 3. YThese 4 which is .narrowest at its intermediate portion and tapers or increases in diameter to both ends so' as to elfectually interlock in the pocket and `be self-retaining. To further secure the inserts in the tire an openwork fabric binder may be embedded in the material of the tire and extend across the intermediate portions of all of the pockets so that the cementitious material, when placed in the pockets, will pass'through the meshes of the binder, and, when set, will efl'ectually interlock with the binder and prevent possibility of accidental disconnection.

As the material is placed in the pockets when wet, it will entirely fill the pocket and when thoroughly set, will form a permanent part of the tire and present a wearing surface to the tread of the tire which not only increases the wear of the tire, but, as above stated, prevents punctures and blow-outs, as well as skidding orl slipping. of the tire.

Thematerial employed to form the inserts is preferably Portland cement, but it is obviously within the spirit of my invention to employ any cementitious material which can be applied ina wet or plastic' form andwhich, when dry, will set and form, in eiect, artificial stone. r

Itherefore do not wish to be limited to the precise details set forth, but consider myself at libertyv to make suchchanges and alterations as fairly ,fall within the spirit and scope of the appended claims.

I claim: l l

l. A tire having a flexible tread portion and having pockets in its tread portion, cementitious inserts in the pockets, and a binder embedded in, the tire and extending through the inserts.

2. A tire having a flexible tread portion and having pockets in its tread portion, -cementitious inserts in the'v pockets, and a binder embedded in the tire and extending through the inserts, said binder consisting of an open woven fabric. f
